To be honest, this is not the best idea in the world. Simply because the best for steem is to keep STEEM. Not selling it for EUR or USD.
Helping people cash out their steem is acceptable at the beginning but it can not be an end in itself. In the future, ​We can expect to pay whatever we need in Steem ... one day maybe ;)
but like everyone, i would like my card to use some money. But i still encourage people to believe in Steem and buy Steem Power ;)
